How do I know if I'm getting better?

SE wastes resources / cash for an app noone is using...., but can't give console players a parser -_-

In-game parsers aren't generally a thing in any MMO, at least not ones provided by the developers. "Damage Reports" that just tell total damage are a little more common...and even this game has that in PvP (such as in the frontline report at the end).

But a damage parser that tracks the way ACT does here or Recount does in WoW is almost always handled by mods, not the developers.

Some games simply have significantly better mod-support (or mod-support at all).
